Divided - into - segments liquid - level measuring instrument divides measuring range into different lays ( every lay corresponds to a fixed space height ) using equal - structure physical electrodes , combines analog circuit technology , digital circuit technology and singlechip technology to detect capacitor lay by lay 分段式液位测量是利用等结构物理电极把整个测量范围分成不同层面,每个层面对应着固定的空间高度,用模拟电路技术、数字电路技术及单片机技术相结合,逐层测量电容。
Meantime , through the analyses of " infinite extension of rights " and " finite extension of rights " , the author thinks " finite extension of rights " should be adopted in our country and other developing countries . considering the social interests , benefits of layout - design ' s authors , interests of developing countries and renewal of integrated circuit technology , the author points out that 10 years in protection of layout - design is somewhat long 在权利内容方面,复制权和商业利用权的规定也颇有特色,而且,在当今世界,存在着权利效力范围的“权利有限延伸论”和“权利无限测申论”之争,无论从集成电路发展的状况,还是从布图设计权产生的条件,我国及广大发展中国家都应采“权利有限延伸论” 。
A novel low mechanical hysteretic ceramic capacitive pressure transducer has been made , by using of ceramic sealing technology ; integrate circuit ( ic ) technology and thick film plane fixing circuit technology . this transducer is made of a deformable ceramic diaphragm and a ceramic base plate , between which has an air cavum . a coaxial gold electrode was fired onto the diaphragm and the base plate 本文利用新型陶瓷技术、集成电路技术和厚膜平面安装电路技术,采用零力学滞后的陶瓷和陶瓷密封材料进行设计制造了一种非充液干式的电容式压力传感器,该压力传感器由较厚的陶瓷基体和较薄的陶瓷膜片构成,中间形成一空气介质腔,在基座和膜片之间内置同轴的双电极,组成两个电容,当膜片承受压力时发生位移,使电容量产生变化,经后置处理电路直接转换为可输出的直流电压信号。
